I'm wanting to building a box for 2 15"s with a keft port. It will be subs up, port back. My question is......
1) port across the bottom from end to end?
2) Port center top to bottom?
3) Port on 1 side (either or) top to bottom?
I'm not sure what, if any difference it will make. It'll be going in a '92 4dr blazer.
